摘要
框架结构中梁柱的连接往往是半刚性的,设计中把梁柱连接假定为完全刚接或完全铰接都是不合理的。在对半刚性框架和刚性框架受力变形分析的基础上,综合框架正常使用极限状态和承载能力极限状态两种状态,建立了竖向荷载作用下梁柱连接刚性判别准则。
Generally the frame beam-colunm connections are semi-rigid. It was unreasonably to assume that the connections were rigid or normally pinned in design. Based on the internal force and deformation of the frame structure, considering two states including serviceability limit state and ultimate limit state, criterion to distinguish the rigid connection, semi-rigid connection and flexible connection under vertical load is discussed.
